Pabodi yokhazikika imasunthira tulo tating'ono tating'ono ta Bluetooth, tomwe timavalira

Antena chilimbikitso?

"Tekinoloje iyi imathandizira kusintha njira zofananira ndi miyambo ya antenna ndi gulu latsopano la otchedwa antenna boosters, loperekedwa mwa zida zazing'onoting'ono kuchokera pa alumali Imeneyi "adapangidwa kuti ipangire Bluetooth m'manja opanda zingwe zokhala ndi malo ochepa."

"Sizifunikira chilolezo kupitilira momwe zingakhalire," woyang'anira malonda wa kampani Raquel Arribas adauza Electronics Weekly. "Popeza chipangizochi sichifunikira chilolezo pa PCB kupitirira gawo lawolawo, mutha kugwiritsa ntchito gawo lomwe lili chapambali kuti mupange zina mu PCB."

40 x 80mm board (gawo EB_NN03-320-m-BT) ili ndi masamba awiri kuti apeze antenna ndipo cholinga chake ndikuwonetsa kuti chigawocho chitha kukhazikitsidwa m'mphepete mwa PCB kapena pakona ya PCB.

Imakhala ndi chingwe cholumikizira ndi SMA cholumikizira antenna, kuphatikiza mawebusayiti ofunikira ofunikira (atatu a SMD capacitors, ndipo amagwira ntchito kuyambira 2.4GHz mpaka 2.5GHz.

Kuyang'ana tsamba lazal board:

Kuchita kwa tinyanga kumakhala kokhazikika ndi malo omwe amagwirira ntchito kuti zida zosiyanasiyana zokhala ndi ma board osiyana siyana osindikizidwa, zigawo zina zapafupi ndi antenna, mabatire a LCD, mabatani, zokutira ndi zolumikizira zimakhudza ntchito ya antenna. Momwemo, ndikulimbikitsidwa kwambiri kuyika mapadi omwe amagwirizana ndi 0402 ndi 0603 SMD pazinthu zofananira kwambiri pafupi momwe zingathere kufikira chakudya cha antenna. Chitani izi mderalo la ndege, osati pamalo oyandikira. Mwa kukonza ulalo wofananira mumapangidwe anu omaliza ndi zigawo zanu zomaliza (mabatire, zowonetsera, zophimba, ndi zina) mudzatha kukhathamiritsa machitidwe a antenna popanda kusintha gawo la antenna.

Antenna weniweni ndi cholinga chophatikizira - ili ndi ndakatulo imodzi yogwiritsira ntchito ma frequency a Bluetooth (omwe amagwiritsidwa ntchito pochita izi) ndi yachiwiri yogwira ntchito ku GNSS (satellite navigation satellite, ngati GPS). Pali bolodi yachiwiri yowunikira yomwe imagwiritsa ntchito madoko onsewa.
